Answer:22 and 21
Step-by-step explanation:
Answer:
y = 6x + 18
Step-by-step explanation:
so first write y = 6x + b (because you have the slope) now to find the y-intercept input the point (-2, 6) and do algebra
6 = 6(-2) + b
6 = -12 + b
b = 18
The formula to calculate the z-score of a certain value is:
z = (x - (mean))/(standard deviation)
In this example, the x-value is 450, the S.D. is 100, and the mean is 500.
So, substitute these values into the formula.
z = (450-(500))/100
z=-50/100
z=-0.5
Therefore, the z-score is -0.5.
